Errata
get stm32 facts, known chip problems, and source documents in your coding agent.
errata gives coding agents stm32 facts from official documents. ask about a part and a task. errata returns registers, pins, electrical limits, known chip problems, and sources. if a fact is missing, errata says so.
try it without an account
the free trial needs no download or api key.
start here
connect a coding agent
add errata to codex, claude code, cursor, or vs code.
choose an mcp tool
find the tool for part search, hardware facts, or a setup review.
check a hardware setup
check the exact part, limits, known problems, missing facts, and sources.
use the rest api
get the same stm32 facts over http.
what errata does
- every fact links to its source and includes the limits that apply.
- errata asks you to choose when a name matches more than one part.
- errata searches only the exact part, package, and chip revision that you select.
not_indexedmeans that errata does not have the fact.no_matchmeans that the facts do not answer the question.- every response includes a data version that you can save and use again.

mcp and rest are free during beta. no account or api key is required. the public limit is 10 requests per minute for each ip address.
what catalog coverage means
a listed part does not mean that every fact is available
errata can find a part even when an official document does not contain the
fact that you need. before you use an answer, read status, gaps,
conditions, and provenance.
